I installed a almost new Yamaha digital tach in my boat but need a little more help.<br /><br />What are the set and mode buttons for on the tach? I know if you press mode the overall hour meter goes off but thats about it.<br /><br />If you have a Yamaha digital tach could you inform me of what the buttons are used for. i don't think they are for much but I don't know so...<br /><br />Thanks<br /><br />Searun1
